    OT question: As a thought experiment you can have a black hole with a schwarzschild radius long enough that the gravitational pull of the black hole to say 1 kgr is 10N, which is exactly the gravitational pull of earth on 1 kgr on the surface of the planet. (I know it needs huge mass, but it’s a thought experiment). So, when that 1 kgr passes through the event horizon (and the pull is 10N) what exactly forbids it from coming out again?
